Description

Title of the invention: Antiperspirant cosmetic composition technical field

[0001] The present invention relates to a composition comprising at least one antiperspirant active ingredient, as well as a cosmetic antiperspirant process for human keratinous materials, preferably from the skin, implementing this composition. Context of the invention

[0002] In the field of cosmetic products, it is well known to use topical antiperspirants containing substances that limit perspiration and / or deodorants containing substances that limit the development of body odor. The antiperspirant and / or deodorant effect is hereinafter abbreviated as the AT / DO effect.

[0003] In the field of deodorants and antiperspirants, there are many dosage forms: stick, roll-on, cream, aerosol, or spray, giving consumers a wide choice. While solid or creamy formulas most often use contact dosage forms such as roll-on or stick, AT / DO formulas in liquid form, generally as an aerosol or spray, are more pleasant and easier to apply, particularly because they avoid direct contact between the skin and a dispenser nozzle, and can be perceived as more hygienic.

[0004] Aerosol formulation is one of the most widely used forms in the deodorant and antiperspirant sector. An aerosol formula is a suspension of particles or liquid in a liquefied or compressed gas, the "propellant gas." A spray from an "aerosol" is characterized by its sensory qualities (softness, strength, dry touch), its flow rate, its spray angle, the size of the particles or droplets, and its precision.

[0005] In cosmetics, most of the propellants still used are liquefied and hydrocarbon in nature. To ensure complete homogenization of the formula (the "juice") and the hydrocarbons present, it is recommended to shake the bottle before use. This allows the consumer to benefit from a homogeneous juice / gas mixture throughout the product's lifespan. This step is necessary to maintain the product's effectiveness between its first and last use, and also prevents the risk of clogging of the aerosol device after spraying, due to the drying of insufficiently dispersed particles.

[0006] The proposal of eco-responsible solutions, such as the formulation of environmentally friendly cosmetic products whose design and development take environmental issues into account, is becoming a major concern in order to contribute to meeting global challenges. It is therefore essential to designing products and / or compositions that allow certain materials / compositions to be replaced by alternatives with a better environmental footprint.

[0007] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or with a good naturalness index, while reducing the use of petrochemical-derived compounds.

[0008] The aim is to design cosmetic products whose manufacture, marketing, and use generate the least possible impact on the environment, particularly by reducing greenhouse gas emissions. There is therefore a real need to develop AT / DO aerosol formulas propelled not by hydrocarbons in liquefied gas form, but by compressed air.

[0009] Compressed air aerosol products already exist in the cosmetics field, notably alcoholic deodorants using air as a propellant, or those employing Bag-on-Valve (BOV) technology and offering a deodorant without petroleum gases (butane, propane). Currently, there is no compressed air-propelled antiperspirant aerosol on the market, nor is there an antiperspirant formula with a rheology suitable for this type of dispensing. Furthermore, conventional non-aerosol liquid formulations in vapor / spray form, containing a deodorant and / or antiperspirant active ingredient, are known for their tendency to run on the skin after application and to leave a sticky residue.

[0010] There is therefore a real need to develop a sprayable AT / DO liquid composition that can be dispensed in fine droplets, particularly using an aerosol with the most natural propulsion possible, especially compressed air, and that is both stable and free from the risk of aerosol clogging, while meeting consumer requirements in terms of efficacy and sensory appeal, with a non-sticky residue and rapid drying, for a dry and fresh effect. The present invention also aims to provide a sprayable antiperspirant composition, particularly one that can be propelled with a compressed gas (air or nitrogen) (preferably continuous spray) or sprayed using a conventional pump (intermittent spray), and without a sticky effect.

[0011] The applicant has surprisingly discovered that all of these objectives can be achieved by the cosmetic composition according to the present invention. Summary of the invention

[0012] According to a first aspect, the present invention relates to an antiperspirant cosmetic composition comprising:

[0013] - at least one C2-C4 monoalcohol,

[0014] - water,

[0015] - at least one antiperspirant active ingredient selected from salts and complexes aluminum and / or zirconium,

[0016] - at least one C2-C8 polyol,

[0017] in which the weight ratio of the quantity of ethanol to the quantity of water is greater than 1.

[0018] According to a second aspect, the present invention relates to an antiperspirant cosmetic product comprising an aerosol device pressurized by a compressed gas, preferably non-flammable and non-polluting, such as compressed air or nitrogen, comprising a container containing a composition according to the invention, the device being intended to distribute said composition in the form of a spray, preferably continuous, in particular without emission of greenhouse gases from a liquefied hydrocarbon; said container being preferably made of aluminum, preferably recyclable, or of a transparent material, preferably glass or plastic, such as PET.

[0019] According to a third aspect, the present invention relates to a cosmetic treatment method for body odors related to human perspiration, particularly axillary odors, and possibly human perspiration itself, consisting of applying an effective quantity of the cosmetic composition as defined according to the invention to the skin surface, particularly in the form of a spray, preferably continuous, notably using an aerosol device, particularly without emitting greenhouse gases. Furthermore, said method may include agitating a composition according to the invention before its application, preferably by spraying, to the skin surface. Detailed description of the invention

[0020] In the context of the invention, and unless otherwise stated, the term "deodorant active" or "deodorant agent", hereinafter referred to as "DO active", means any substance capable of masking, absorbing, improving and / or reducing the unpleasant odor resulting from the decomposition of human sweat by bacteria.

[0021] In the context of the invention, and unless otherwise stated, "antiperspirant active" or "antiperspirant agent", hereinafter referred to as "AT" active, means a molecule which, on its own, has the effect of reducing the flow of perspiration, of reducing the sensation on the skin of moisture related to human sweat.

[0022] The composition according to the invention is a cosmetic composition, i.e., found in a cosmetic medium.

[0023] The process of the invention is particularly advantageous for treating body odors related to perspiration in the armpits.

[0024] The compositions, particularly cosmetics, according to the invention comprise a physiologically acceptable medium. For the purposes of the present invention, a "physiologically acceptable medium" means a medium suitable for administering a composition to the skin. A physiologically acceptable medium is generally odorless and free from unpleasant appearance, and is perfectly compatible with the topical route of administration to the skin. In the present case, where the composition is intended to be administered by application to the skin surface, such a medium is considered physiologically acceptable in particular when it does not generate stinging, tightness, or redness unacceptable to the user.

[0025] In particular, the composition is suitable for application to the skin surface. Thus, the physiologically acceptable medium is preferably a cosmetically or dermatologically acceptable medium, that is to say, without unpleasant odor, color or appearance, and which does not generate tingling, tightness or redness unacceptable to the user.

[0026] The composition may then include all the constituents usually used in the intended application. Of course, a person skilled in the art will take care to choose any additional compound(s), and / or their quantity, in such a way that the advantageous properties of the compounds according to the invention are not, or not substantially, altered by the intended addition.

[0027] Other features, aspects and advantages of the invention will become apparent from the detailed description that follows.

[0028] In the context of the present invention, the term "free of" indicates that the composition comprises less than 0.5% by weight, or even less than 0.2% by weight, and more particularly less than 0.1% by weight of the compound in question, relative to the total weight of the composition. Preferably, the composition is free of the compound in question.

[0029] For the purposes of the present invention, and unless otherwise indicated, the expression "at least one" is equivalent to "one or more" and, unless otherwise indicated (such as "more than...", "less than" or "between X and Y"), the bounds of a range of values ​​are included in that range (for example "in the range of X to Y"). Composition

[0030] According to a first aspect, the present invention relates to a composition as defined above.

[0031] The applicant found that, surprisingly, the addition of a polyol such as glycol in a specific ratio to a hydroalcoholic antiperspirant formula (particularly one containing aluminum salts) allowed for both: - to package and deliver said formula in an aerosol container (made of aluminium or PET) in spray form (including continuous spray), without the aerosol nozzle outlets becoming blocked due to the high volatility of ethanol and water and the crystallization of aluminium salts in these outlets; and - to offer an AT / DO formula perceived (sensory test) as effective for the AT / DO effect, without stickiness, and potentially more natural than current AT / DO formulas on the market, because it is particularly suitable for continuous spray aerosol devices, without petroleum-based propellant gas.

[0032] The transparency of the formula is another advantage for consumers, who appreciate the clean and fresh effect of this galenicity. Aqueous composition

[0103] The composition according to the invention can be obtained in a conventional manner by a person skilled in the art.

[0104] The composition according to the invention is preferably liquid.

[0105] By "liquid," it is understood that the composition is sufficiently fluid to be shaken and / or to be sprayed. The composition according to the invention is therefore not solid, and in particular is neither a stick nor a roll-on.

[0106] Advantageously, the composition according to the invention has a texture very similar to water, more precisely, the composition has a viscosity very close to that of water.

[0107] Preferably, the composition of the invention is in the form of a transparent and colorless water, preferably having the same appearance as water, and in particular the same texture as liquid water under ambient conditions of temperature (25°C) and pressure (100 kPa).

[0108] More particularly, the viscosity of the water defined in the present invention is less than or equal to 500 mPa.s, preferably less than 200 mPa.s, more preferably less than 100 mPa.s, and even more preferably less than 50 mPa.s, or even less than 20 mPa.s, or better yet less than 10 mPa.s. For example, the water of the present invention has a viscosity of 1.2 mPa.s.

[0109] The composition of the invention is preferably a transparent liquid which appears clear, colorless and transparent like water to simulate the physical appearance of water.

[0110] The term "transparent" in the context of the present invention means that the composition has a turbidity less than or equal to 300 NTU. The transparency of a composition can be measured by its turbidity, and NTUs (Nephelometric Turbidity Units) are the units of measurement for the turbidity of a composition. Turbidity measurement can be performed, for example, with a model 2100P turbidimeter from HACH Company, the tubes used for the measurement being referenced AR397A cat 24347-06. Measurements are carried out at room temperature (20°C to 25°C). The two distinct phases of the composition according to the invention generally have a turbidity ranging from 0.1 to 300 NTU, and preferably from 1 to 100 NTU.

[0111] The composition according to the invention can be contained in a device allowing Its application, particularly by spraying, onto the skin. Preferably, this device is a pump bottle, or bottle equipped with a spray device, or an aerosol bottle containing compressed gas (air or N2).

[0112] The present invention therefore also relates to an aerosol device comprising the composition according to the invention, said device being preferably pressurized by a compressed gas, preferably non-flammable and non-polluting, such as compressed air or nitrogen, comprising a container containing a composition according to the invention, the device being intended to distribute said composition in the form of a spray, preferably continuous, in particular without emission of greenhouse gases from a liquefied hydrocarbon; said container being preferably made of aluminium, preferably recyclable, or of a transparent material, preferably glass or plastic, such as PET. Aerosol device

[0113] The aerosol operates on the principle of spraying by expansion of compressed gas. The product to be sprayed is contained in a sealed container, under pressure from a propellant gas, preferably non-polluting. Activating the valve releases the compressed gas, which carries the product with it, for example, in the form of a fine and homogeneous spray.

[0114] The aerosol comprises a container, a valve, a diffuser, a propellant gas and the cosmetic composition.

[0115] The container is made of, in particular, preferably recyclable aluminum or preferably recyclable PET, and is of variable shape depending on the requirements (cylindrical, ergonomic, etc.) and is designed to withstand the internal pressure of the propellant gas. The valve is, in particular, a continuous-action valve for constant, user-controlled spraying, operated by a mechanical actuation mechanism triggered by finger pressure on the diffuser. Preferably, the valve ensures a perfect seal to prevent any leakage of gas or product. The diffuser is shaped to suit the desired application (wide mist, precise jet, etc.). Advantageously, it is made of a plastic material compatible with the cosmetic composition and resistant to pressure. Preferably, the propellant gas is a non-flammable, non-polluting compressed gas (e.g., compressed air, nitrogen), with the pressure adjusted to ensure optimal spraying of the cosmetic composition..

[0116] According to the invention, the spraying is advantageously continuous, meaning that the product is delivered in an uninterrupted and uniform flow as long as the user maintains pressure on the aerosol's push button. This type of spraying is generally achieved by means of a special valve integrated into the aerosol. This valve, called a "continuous valve" or "metering valve," is designed to maintain a constant flow of the product when the push button is pressed.

[0117] Thus, the composition according to the invention is released at a steady rate, creating a homogeneous jet or mist. This differs from traditional aerosols that deliver the product in separate "puffs" with each press. The continuous spray gives the user greater control over the amount of product applied. The spray time can be easily adjusted to target a specific area or achieve the desired intensity. Furthermore, the continuous diffusion of the composition allows for more uniform application, preventing build-up or missed areas.

[0118] The cosmetic composition is formulated to be compatible with the propellant gas and the spraying system.

[0119] The choice of propellant gas will depend on several factors, including the viscosity of the composition, the desired particle size, and the desired environmental impact.

[0120] Preferably, the pressure in the container containing the composition is in the range of 200,000 (2 bars) to 1,500,000 Pa (15 bars); more preferably from 300,000 (3 bars) to 1,300,000 Pa (13 bars); more preferably still from 400,000 (4 bars) to 1,000,000 Pa (10 bars); better from 500,000 (5 bars) to 1,000,000 Pa (10 bars); even better from 600,000 (6 bars) to 1,000,000 Pa (10 bars).

[0121] The aerosol according to the invention preferably sprays the composition in fine droplets, preferably in the form of a continuous spray.

[0122] The aerosol according to the invention does not spray said composition in the form of foam.

[0123] During the manufacture of the device according to the invention, the propellant gas is added under pressure to a composition according to the invention; said composition being contained in the aerosol, in particular in the container.

[0124] The invention also relates to a cosmetic skin treatment method comprising at least one step of spraying a composition as described above onto the skin, using the aerosol device according to the invention.

[0125] Preferably, the aerosol device according to the invention is free of organic propellant.

[0126] By "organic propellant", for the purposes of the invention, means a propellant derived from petroleum refining (i.e. petroleum-based gas), and more preferably chosen from volatile hydrocarbons and ethers.

[0127] The expression "devoid of organic propellant" means that the composition does not include an organic propellant, or that the organic propellant(s) present in said composition are included in a total content of less than or equal to 1% by weight, preferably less than or equal to 0.5% by weight, more preferably less than or equal to 0.1% by weight, better less than or equal to 0.05% by weight, relative to the total weight of said composition, and even better free of propellant (0% by weight).

[0128] As organic propellants or gases, the following may be cited in particular: volatile hydrocarbons, possibly halogenated (for example chlorinated and / or fluorinated); dimethyl ether; and mixtures thereof; in particular dimethyl ether, C3-C5 alkanes, trichlorofluoromethane, dichlorodifluoromethane, chlorodifluoromethane, 1,1,1,2-tetrafluoroethane, chloropentafluoroethane, l-chloro-l,l-difluoroethane, 1,1-difluoroethane, 1,3,3,3-tetrafluoropropene, and mixtures thereof; and more particularly C3-C5 alkanes, such as propane, isopropane, n-butane, isobutane, pentane, and mixtures thereof. Process

[0129] The present invention also relates to a cosmetic process for the treatment and / or care of human keratinous materials, preferably from the skin, comprising The agitation of a composition according to the invention, followed by its application to the surface of said keratinous materials. The agitation is typically carried out manually.

[0130] The present invention also relates to a cosmetic process for treating human perspiration and / or body odors related to human perspiration, consisting of shaking a composition according to the invention, and then applying it to the surface of a human keratinous material, preferably by spraying or misting, onto the surface of the skin.

[0131] Concrete, but by no means limiting, examples illustrating the invention will now be given. Examples

[0132] The following examples provide a better understanding of the invention without, however, being limiting in nature.

[0133] The compositions of the tables below were prepared by mixing the ingredients of the tables, then applied and evaluated according to the protocols listed and described below.

[0134] The formulas were evaluated and sprayed from the following aerosol dispensing device:

[0135] - Aluminum aerosol container, 150x45cm, Maximum capacity 210mL

[0136] - Valve (Supplier: Precision): IxGI 0.4 / RI 0.5 / PGA 0

[0137] (GI = jet = 0.4 mm; RI = Internal Restriction = 0.5 mm, PGA = Additional Gas Intake = 0 mm)

[0138] - Swirl nozzle (Supplier: Lindal): outlet orifice = 0.33 mm.

[0139] This Packaging / Formula configuration gives the following characteristics at the outlet of the aerosol:

[0140] - Average output flow rate: 0.49 g / s

[0141] - Return rate: 94.4% > 90%

[0142] - Droplet size (Granulometry): 106 to 171 pm

[0143] - Appearance of the Spray: round and homogeneous spot Example 1#: Functionality Test

[0144] Test protocol:

[0145] 4 aerosols of each tested formula CC5, C6, C7 from the table, are kept at ambient temperature (25°C) for performing daily and weekly functional tests:

[0146] 2 aerosols are activated each day (daily test).

[0147] 2 aerosols are activated each week (weekly test).

[0148] Every day and every week the aerosols are activated 2x5 seconds under an ATEX hood in a beaker.

[0149] Weekly operations are carried out for up to 9 weeks, which is equivalent to 2 months of classic stability.

[0150] Formulas tested:

[0151] [Tables 1] C C5 C6 C7 ALCOHOL DENAT. 77.60 67.00 67.00 ALUMINUM HYDROCHLORIDE ATE 10.60 10.60 10.60 WATER 10.60 10.60 10.60 GLYCERIN 10.60 PROPYLENE GLYCOL 10.60 FRAGRANCE 1.20 1.20 1.20

[0152] Results:

[0153] The 2 aerosols with composition C5 completely clog at room temperature one week after packaging.

[0154] The 2 aerosols with composition C6, C7, at 10.6% in glycerin, respectively in propylene glycol, do not clog at room temperature after 9 weeks, i.e. after 2 months of classic stability.

[0155] Conclusion:

[0156] The addition of glycol-type polyols, such as glycerin or propylene glycol, solved the problem of the aerosol clogging during functional tests.

[0157] The polyol thus used in the compositions according to the invention made it possible to lubricate the walls of the dip tube and those of the nozzle distribution channels and thus to limit the phenomenon of crystallization of aluminium salts after evaporation of ethanol and water.

[0158] Example 2: Sensory test - Evaluation of the stickiness effect on skin

[0159] Test protocol (to be carried out under an ATEX hood):

[0160] 1. Ensure that the forearm is clean. No product should have been applied to it. This one. Otherwise, wash it under soapy water and dry it.

[0161] 2. Free the clean forearm and place it at the level of the "Arm" line on the workbench.

[0162] 3. Shake the test aerosol 3 times in the other hand, spray with the index finger above from the "Aerosol" line (15 cm from the other line) by making a back and forth on the arm (from right to left).

[0163] 4. Start a timer immediately after spraying and check the stickiness on the skin at 5 seconds, 30 seconds and 1 minute after the formula was broadcast.

[0164] 5. Clean your forearm under soapy water and dry.

[0165] 6. Repeat the test with another formula if necessary.

[0166] NB: Alternate tests on both forearms and do not exceed 2 tests / forearm / day, i.e. a maximum of 4 formulas / day.

[0169] Results:

[0170] Composition Cl, containing 4% glycerin, leaves a slightly sticky finish on the skin after application. After 30 seconds, the skin is soft and no longer sticky. The same is true after 1 minute.

[0171] Composition C2, containing 5.65% glycerin, leaves an acceptable sticky finish once the product is applied to the skin. After 30 seconds, the skin is soft and not sticky. The same is true after 1 minute.

[0172] Composition C3, containing 6% glycerin, leaves a significant sticky finish on the skin. This effect is always present 30 seconds and then 1 minute after the formula is applied.

[0173] Formula C4, containing 5.65% propylene glycol, leaves a noticeably sticky finish once applied to the skin. After 30 seconds, the skin is slightly sticky. The same is true after 1 minute. This formula is less sticky than formula C3.

[0174] Conclusion:

[0175] The more polyol there is in the formula, the more the formula helps to counteract the problem of clogging in the nozzle's distribution channels. Composition C2 according to the invention offers the best compromise between the (low) stickiness of the formula deposited on the skin and the (low) clogging of the aerosol.

[0176] Furthermore, at iso-concentration in polyol (C4: propylene glycol and C2: glycerin), propylene glycol leaves a more pronounced sticky finish on the skin compared to the C2 formula with glycerin.

[0177] Example 3: Study of the antimicrobial / bactericidal effect - T is killing

[0178] Test protocol:

[0179] Test for the enumeration of the bacterium Corynebacterium xerosis, one of the bacteria responsible for bad axillary odors, over time.

[0180] Introduction of the tested formula into a medium containing these bacteria and enumeration of these bacteria over time in order to study the antibacterial power of the formula.

[0185] The antibacterial action kinetics between T0H and T2H are 1.93 times faster for the composition according to the invention C9 than for the comparative composition CC8. The aluminum salts act immediately against bacteria.

[0186] Ethanol helps to eliminate bacteria more quickly in the case of a composition according to the invention C9, than for a comparative composition CC10.

[0187] A second Killing test was performed between T0H and T2H at shorter control times to refine the study.

[0188] Killing Test Results #2: Controls at T0H, T15min, T30min, T1H, T2H:

[0190] The antibacterial action kinetics of composition C9 according to the invention is very good and rapid, with an antibacterial performance (<200) as early as 15 min after application of the formula in the medium containing the Corynebacterium Xerosis bacteria responsible for bad odors.

[0191] Conclusion of the two tests performed:

[0192] Formula C9 according to the invention, combining aluminium salts and ethanol, exhibits good and rapid antibacterial activity because within 15 minutes of application in the medium, no more Corynebacterium xerosis type bacteria were detected.

[0193] Formula C9 according to the invention exhibits superior antibacterial performance due to the combination of ethanol and aluminum salts, compared to the comparative compositions CC8 (ethanol alone) and CC10 (ACH alone). Example 4#: Microfluidic Test

[0194] Test objective:

[0195] Evaluate the antiperspirant performance of a formula. The objective of this test is to mimic in vitro what happens in vivo on the armpits.

[0196] Test protocol:

[0197] The tested formula is introduced into four microchannels in a humid environment at approximately 35°C. Artificial sweat comes into contact with the four channels, forming the plug / precipitate present in the sweat ducts. Finally, a compressed air pressure gradient is applied to these plugs in the channels, and once the plug is exposed to a given pressure, the antiperspirant performance of the following formulas is evaluated. The higher the pressure required to eliminate the plugs, the better the antiperspirant performance of the formula.

[0198] Formulas tested:

[0199] [Tableauxô] Eyelash CC12 CC13 ALCOHOL DENAT. 73.15 41.87 ALUMINUM CHLOROHYDRATE 10.60 10.60 10.60 WATER 10.60 83.75 41.88 GLYCERIN 5.65 5.65 5.65 Results: Pressure exerted (mBar) 2348 1774 860

[0200] Conclusion:

[0201] Of the three formulas tested, the maximum pressure measured to eliminate the blockage present in the channels is the highest for Cil. Thus, the combination of ethanol and aluminum salts in the Cil composition according to the invention improves the antiperspirant performance of the formula. Example 5#: Evaluation of deodorant effectiveness
